In plain English
Arthur J. Gallagher is the world's third-largest insurance broker — a middleman that never carries the risk itself. It places cover for mid-sized companies, governments and individuals with the insurers and reinsurers that underwrite it, earning commissions and fees, and grows relentlessly by swallowing smaller agencies (the ~$13.45B AssuredPartners deal in 2025 was its biggest ever).
